Description

[0002] The mine motor is a special industrial motor designed for the harsh environment of the mine. It needs to meet the requirements of high strength, explosion-proof, high protection level and high performance. Therefore, the motor shell is often designed to consider the protection, durability and heat dissipation requirements, and is made of high-strength cast iron material with a certain thickness. In order to improve the explosion-proof performance and protection performance, the motor shell is often tightly connected and sealed by welding to prevent flame from leaking and to adapt to high dust and high humidity environments.

[0003] In the existing mine motor, the motor shell is often placed on a rotating base. After the shaft center is determined by centering and clamping, the motor shell is rotated while the connecting part is welded, so that the end cover is welded on the motor shell. However, part of the motor shell is asymmetric and irregular, and it is difficult to determine the position of the shaft center by centering and clamping. When the rotation is controlled, the shaft center deviates, resulting in poor welding effect. The mine motor shell is made of high-strength cast iron material with a certain thickness, and its weight is relatively large. It is very difficult and laborious to arrange it on the rotating base, which seriously reduces the welding efficiency of the motor shell, and there is a risk of slipping and bruising during the handling of the motor shell.

[0032] In the above, the sliding base 1 is pushed, and the mine motor shell is put into the sliding base 1 and the C-shaped surrounding module 2 from the front side opening. The end cover to be welded is placed on the top of the motor shell through the motor shaft, and is clamped on the motor shaft through the axial positioning module 6, so as to determine the shaft of the motor and make it coincide with the shaft of the sliding base 1 and the C-shaped surrounding module 2. The clamping positioning module 3 is adjusted to make the C-shaped surrounding module 2 clamped and fixed on the motor shell. The end cover is tightly pressed on the top of the motor shell through the end cover positioning module 7, and the position and angle of the welding module 8 are adjusted. The welding module 8 is started to weld, and the rotary drive module 4 is started to make the sliding base 1 and the C-shaped surrounding module 2 relatively rotate slowly. Because the motor shell is heavy and is directly placed on the ground, the sliding base 1 drives the lifting module 5 at the rear side to rotate around the motor shell, and the welding module 8 rotating with the lifting module 5 melts and welds the fine gap between the motor shell and the end cover. After one round around the motor shell, the motor shell welding work is completed.
